Goldschmidt has been dealing with leg tightness. He did not play Thursday, and is not in the lineup for Friday's game due to the issue. Manager Kirk Gibson said Goldschmidt would return to the lineup Saturday.
Goldschmidt hit .302/.401/.551 in 602 at-bats last year.
"Daniel looked good," pitching coach Don Cooper told the Chicago Tribune. "...It sounded like a bowling ball hitting the glove. He was throwiing kind of a heavier ball."
Well, who will make his game debut Sunday, is a longshot in the battle for the closer job, which is headed by favorite Nate Jones and Matt Lindstrom, both of whom have been sidelined with nagging injuries.
Luebke had a second Tommy John surgery in February, so the move shouldn't come as a surprise. The team claimed outfielder Alex Castellanos off waivers, and had to make room for him on the 40-man roster.
Doubront appears set to secure a rotation spot after compiling an 11-6 record and 4.32 ERA in 2013. His ERA dropped considerably as he pitched to contact more successfully than he did in 2012, when he struck out more than a batter an inning. Doubront still managed to fan 139 in 162 1/3 innings last year.
Castellanos was designated for assignment Wednesday. San Diego has moved pither Cory Luebke to the 60-day disabled list in order to make room for Castellanos on the 40-man roster.
Cobb is listed as the second starter behind ace David Price. He won 11 of 14 decisions with a 2.76 ERA in 22 starts a year ago.
The issue is likely not that serious, but the team will give Rosario some time to rest. Rosario should return to the lineup soon. He hit .292/.315/.486 in 449 at-bats last year.
The first returns were encouraging for right-hander
Jimenez was among the best pitchers in the game from May forward last season after a terrible 2012. He left Cleveland for free agency and signed a four-year contract worth $50 with Baltimore.
Rutledge missed six days due to an ankle injury. He was able to pass all his tests this week, and was deemed ready for game action. Rutledge will compete for a utility spot on the team's 25-man roster. He hit .235 in 285 at-bats last year.
